procedure The laboratory waste management practices will outline safe handling and disposal of laboratory waste into either the Sandstone Gully Tailings Storage Facility as per condition E7 of the EA or taken offsite for disposal. 4.7 Regulated Waste As the site is currently not operational and only early work construction is being undertaken, there is currently no regulated waste being kept on site. Temporary regulated waste pertaining to the servicing of mine vehicles (used oil filters and oil) are stored in designated blue bins and removed and disposed of by the servicing contractor. Once the site is operational and regulated waste is produced it will be stored in appropriate containers that are labelled and taken off site for disposal by a contractor. The Sandstone Gully TSF is not yet constructed. During October 2024 EPML00433013 was amended to authorise the temporary discharge of four (4) million dry weight tonnes of processed tailings into OCP, which equates to approximately 2 years of discharge. Recent changes to the mine plan have created a demand for an additional temporary discharge of two (2) million dry weight tonnes of processed tailings into the OCP. An additional amendment is proposed to support the temporary discharge of additional processed tailings into the OCP occur until the Sandstone Gully TSF is constructed. It is proposed that a maximum of six (6) million dry weight tonnes of processed tailings is discharged into the OCP. Tailings will ultimately be disposed in the Sandstone Gully TSF once constructed. 4.8 Tyre Storage The site is currently not operational. Works being done at the site currently are early work activities and construction. With no operational works being undertaken, no tyres are currently stored onsite. Once operations commence, no tyres are anticipated to be stored on-site. If a future need for tyre storage arises, this plan must be updated and adhere to conditions E1 and E2 of the EA. 4.9 Accidents, spills and incidents Potential waste accidents and incidents will be reported as per Incident Reporting Standard Operating Procedure using the relevant Incident reporting process and forms. The process for managing and preventing waste spills and incidents is outlined in the following sections. 4.9.1 Spill Response Only appropriately trained personnel are to undertake the spill response process. Spill response processes are to be implemented only in the instance where the spill poses no immediate threat to personal safety of the individual and other personnel in the vicinity and where the volume of the spill can be managed by the individual. All major spills and those that pose a threat to personal safety or environment will require assistance from emergency services. 4.9.2 Spill Assessment Personnel with the appropriate training are to evaluate the spill location to identify: – The type of material spilled. – The size of the spill and whether the leak has stopped. – Whether two incompatible chemicals have the potential to interact; and – Any unusual features such as foaming, odour, fire, etc. 4.9.3 Spill Emergencies Depending on the assessment of the circumstances associated with the spill, the situation may be evaluated as an emergency, where the circumstances are such that harm can be caused to people or the environment.
